A type of steel which, until only recently, was relatively unknown in the industry is AUS-10. This type of steel is produced by Aichi Steel, from the Japanese city of Tokai. AUS-10 is, because of the high-carbon content, by far the strongest type within the AUS-series.
Even though AUS-10 is still relatively unknown it is definitely not unloved. Leading brand Sakai Takayuki, for instance, has enhanced its 45-layer Damast-collection with this type of quality steel. These stunning knives are absolutely amazing to work with. Why? The 60 HRC knives are rock-solid. As a result the edge is easier to sharpen and will retain its sharpness well.
